No obvious signs of trauma were found on the body of a Menlo Park woman discovered on Mount Tamalpais, officials said Tuesday.

Cause and manner of death are pending toxicology testing, the Marin County Sheriff/Coroner's Office said. The body of the missing hiker, Magdalena Glinkowsi, was located around 9:30 a.m. Sunday.

"There were no obvious signs of trauma that would have resulted in her death," said sheriff's Lt. Jamie Scardina. The lieutenant added that it could take weeks for the toxicology tests to be completed.

Glinkowski, 33, was discovered to be missing in early April when California State Park rangers noticed a car rented in her name was abandoned in a parking lot near Pantoll Campground on Mount Tamalpais.

At the time the body was recovered, there was "no obvious indication of any foul play involved in the investigation of the crime scene and the body," Marin County sheriff's Lt. Doug Pittman said.

The body was found thanks to a tip from Ryan Hutnick of Larkspur, who saw Glinkowski alive when he was going for a Sunday morning run on March 30.

Glinkowski was last seen on a surveillance video that same day, but she lived alone and park rangers didn't figure out she was missing until days later. A massive search was launched the weekend of April 5 and 6.

After learning that Glinkowski was missing from an April 6 Independent Journal story, Hutnick contacted the paper and was referred to officials. Based on Hutnick's information, the search was relaunched Sunday, and Hutnick led them to the area where he saw Glinkowski. Her body was recovered hours later.
